Title: Device for detecting polishing ending point of semiconductor wafer
Inventor: MIHASHI HIDEO
IPC: B24B37/013
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a means which detects the polishing ending point of a thin film on a wiring pattern in a semiconductor wafer polishing process. SOLUTION: Infrared rays 14 emitted from an infrared-ray source 5 become p-polarized light having a wavelength of about 8 μm after passing through a band-pass filter 6 and a polarizing element 7 and the p-polarized light is projected upon an SiO2 film 12 on the surface of a semiconductor wafer 1 in a prescribed area at a prescribed angle through an irradiation lens 8 and irradiation mask 9. The quantity of the infrared rays 14 which are transmitted through the SiO2 film 12 and reflected by a lower-layer pattern 13 is measured by means of an infrared-ray receiving element 11. Since the SiO2 film 12 strongly absorbs the p-polarized light of the light made obliquely incident and having a wavelength of about 8 μm due to the lattice vibration of crystals, the quantity of the received light corresponds to the thickness of the SiO2 film which transmits the infrared rays 14.  Therefore, an end point detecting circuit 15 judges the point of time when the quantity of received light exceeds a threshold as a polishing ending point.

Title: Electrodeless discharge lamp, lighting device for electrodeless discharge lamp and lighting system
Inventor: KAMIMURA KOZO
IPC: H05B41/24
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To provide the lighting system which can prevent optical flux from being lowered due to devitrification, and also can prevent startability from being degraded. SOLUTION: While an electrodeless discharge lamp 6 is switched on a light, halogen is activated in cycle, and there exist a great number of free halogen in the vicinity of the tube wall of a light emitting tube 7. When a part of metal high in reactivity, which are dissociated in the midst of arcing, comes close to the tube wall, it is combined with free halogen so as to thereby produce halogenated metals low in reactivity, the reaction of the tube wall of the light emitting tube 7 and the metals, is thereby avoided. Since devitrification of the light emitting tube 7 and an increase in the quantity of free halogen, are restrained, lowering in optical flux, shaking in an arc, going-out of an arc and lowering in startability can thereby be prevented.

The part 14 enlarges or reduces the form area vertically or in the direction where the positions of other areas are not changed based on a command given from the part 6. Thus the form efficiency is improved for the forming with an uncertain size of the original data.

Abstract: PURPOSE:To obtain sufficient writing and repeating characteristics even with the output from a semiconductor laser that is normally commercially available without damaging high-speed erasure characteristics by determining an atomicity ratio of Te, Ge, and Sb in a recording layer to be within an area surrounded by specific four points in a ternary constitutional diagram. CONSTITUTION:A recording layer of an optical recording medium is made of a material having a composition within an area surrounded by points A(Ge13 Sb29.5 Te57.5), B(Ge13 Sb27 Te60), C(Ge15 Sb27 Te56), and D(Ge15 Sb27.5 Te57.5). The composition containing Te more than that in a GeSb2Te4 stoichiometric composition realizes the decrease of a hex transformation temp. and a sufficient crystallization by a laser annealing, whereby writing and repeating characteristics can be improved. Generally, a deviation in composition from a stoichiometric composition results in the reduction of erasure characteristics and a signal deterioration caused by precipitation or the like at the time of repeating. However, erasure characteristics of the order of 50-70 ns and a repeating number of 5X10<5> or more are ensured. On a quartz substrate, ZnS of 120nm, the recording material of 90nm, and ZnS of 130nm are laminated in this order by a RF magnetron sputtering to form a laminated film.
